When writing a decimal number that is less than 1, you must apply the first zero rule, to clarify the decimal point is there.
The first zero rule is a mathematical rule in which all numbers zero (0) zeroes in the left of the first non-zero number do not modify the real value of the amount to be described, thereby obtaining the same outcomes when adding them.
Therefore, with this data, we can see that the first zero rule indicated that zeroes at the left of the first non-zero number do not change the specified amount.
